The exchange between Epstein (2010) and Klibanoff et al. (2012) identified a behavioral issue that sharply distinguishes between two classes of models of ambiguity sensitivity, exemplified by the Î±-MEU model and the smooth ambiguity model, respectively. The issue in question is whether a...

We develop a novel computerized real effort task, based on moving sliders across a screen, to test experimentally whether agents are disappointment averse when they compete in a real effort sequential-move tournament.  Our theory predicts that a disappointment averse agent, who is loss averse...

We present experimental evidence which sheds new light on why women may be less competitive than men.  Specifically, we observe striking differences in how men and women respond to good and bad luck in a competitive environment.  Following a loss, women tend to reduce effort, and the effect is...

Many interactive environments can be represented as games, but they are so large and complex that individual players are in the dark about others' actions and the payoff structure.  This paper analyzes learning behavior in such 'black box' environments, where players' only source of information...
